VEHICLE SEAT F iled Dec. 31, 1935 Patented Jan. 11, 1938 UNITED STATES VEHICLE SEAT Eric Olle Schiolin, Pontiac, Mich, assignor to General Motors Corporation, Detroit, Mich, a corporation of Delaware Application December31, 1935, Serial No. 56,934

8 Claims.

This invention relatesto seats for automobiles. It is the object of the invention to construct a seat which is easy and economical to manufacture; which may be readily removed from the ve- 5 hicle; which is easy. to adjust; leaves an open space between the bottom of the seat and the floor; and avoids the use of the usual spring cushions.

The objects of the invention are accomplished 10 by constructing a supporting frame composed of tubing having lateral legs of U-shape and a back support of inverted U-shape.' On the frame there is supported a pan having 'a seat portion and a back portion, the pan being provided with flanges at its edges. In the pan there is glued or adhesively secureda rubber cushion or pillow provided with a plurality of air pockets and over the cushion there is adhesively secured a fabric covering. 20 On the drawing:

Figure 1 is a perspective view of the seat with parts broken away better to indicate the structure.

Figure 2 is a section on the line 2--2 of Figure 1. 25 Figure 3 is a perspective view of the bracket secured to the floor-of the vehicle to permit the adjustment of the seat.'

Referring to the drawing, the numeral 2 indicates the seat as a whole. A support for the seat 30 is indicated as a whole at 4 and comprises a tubular framework having the U-shaped legs 6 at the sides and the inverted U-shaped back portion 8. Each U-shaped leg comprises theforward upright the rear upright I2, and the base 35 M, the base 14 resting on the floor to support the frame and seat. Each leg 6 also has the diagonal brace l6 extending from the lower forward corner iii of the U to the top 20 of the rear upright l2. The members l6 are suitably welded 40 in place. Referring to Figure 2, the forward uprights ill of the'two legs 6 are connected by means of. the transverse supporting tube 22.

The inverted U-shaped member 8 at the back 45 comprises the lateral uprights'24 and 26. and the bight member 26. The upper end of the

uprights

24 and 26 is bent outwardly or away from the plane, of the uprights as indicated at 30 in Figure 2. At the mid portion of the bight 28 50 thereis an inwardly bent portion 30, the inner edge of which is in the same plane as the inner edge of the uprights 26 as is'best shown in Figure 2. The

uprights

24 and 26 are contlnuations of the uprights" of the legs '6.

55 A pan 32 is supported on the tubular framework 4. The pan comprises the seat portion 34 and the back portion 36. The front of the seat portion 34 rests on the transverse tube 22 and on the upper end of the inclined member [6 of the legs. The pan portion 34 is welded to the cross member 22, preferably at three points, and to the transverse members l6 at a single point.

The back portion 36 of the pan 32 is suitably weldedat a plurality of points to the uprights 24 and 2'6-and to the indented portion 30 of the bight 28. As will be best seen from Figure 2, the bight 28 of the inverted U-shaped member 8 is spaced from the back portion 36 of the pan so as to form a robe rail.

The pan 32 has the peripheral flange 36 entirely therearound so that the seat portion 34 and rear portion 36 are dish-shaped.

The usual coil springs and necessary supports therefor used in connection with the conventional seat cushions are not used with the present con- 42 the back. Both cushions are provided throughout their extent with rectangular air pockets or columns 44, and both cushions 40 and 42 have adhesively secured thereto the outer fabric covering 46 and 48. This covering 46 and 48 is applied to the pillows or cushions before they are put in place on the pan 32. After the

covering

46 and 48 has been applied, the cushions are stuck or adhesively secured by the use of a suitable paste or glue to the back portions 34 and 36 with the marginal edges of the fabric covering 46 and 48 passing under the flange 38 to conceal the same. After the cushions have been adhesively secured to the back 32 no further labor is necessary and the seat is in its flnal shape. The air pockets formed by the columns-44 and the resili- .40

ency of the rubber itself furnishes a seat and back which are resilient enough to meet all ordinary requirements. v

At the base member I 4' of each leg 6 there is secured the finger 50 provided with a hole 52. The hole 52 is for thepurpose of receiving the shank 54 of a bolt 56, the head 58 of which-is received in the opening 60 in one end of a bracket 68 which is fastened to the floor of the vehicle by screws passing through the openings 10. The shank of the bolt 66 may pass into the slot I2 of the bracket 68 to permit the adjustment of the seat. Suitable wing nuts (not shown) fastened to the threaded portion of the shank 54 holdtheseat in adjustable position. To adjust the seat the wing nuts are loosened and the seats shifted either forwardly or rearwardly and the wing nuts then retightened.

If desired, the bracket 68 may be attached to the top of the floor, or optionally, it may be sunk into the floor and the bracket fastened to the underside of the floor by means of the flange 14.
